Plum Leaf Spot in the Home Fruit Planting

On plum leaves, the spots tend to be smaller, and severely infected leaves often have a tattered appearance. Unlike cherry infection, severe plum leaf infection is often followed by a heavy fruit drop.

Disease Management

Most varieties are susceptible to the disease, so fungicide sprays, along with the sanitation practices suggested for cherry leaf spot, are necessary for control. A light disking should be done just before overwintered spores on leaves are ready to be discharged, about the time of shuck fall.
